3.2 D6513T3C1 BOARD DESCRIPTION: JUMPERS, SWITCHES AND
TEST POINTS
The items described in the following tables refer to the flags in Figure 3-2.
Item #
Reference
Designator
Name
Use
1
JP1
PS_SEL[0]
Two-pin header. When the jumper is installed the on- board
power supply (AC signal) is used to power the demo board.
When not installed, the board must be powered by an external
supply connected to J1. Normally installed.
2,8,9
TP2, TP4, TP6
VA, VB, and VC
Two pin header test points. One pin is the VA, VB or VC line
voltage input to the IC and the other pin is ground.
3,5,6,7
J9, J4, J6, J8
Neutral, VA_IN,
VB_IN, VC_IN
VA_IN, VB_IN, and VC_IN are the line voltage inputs. Each
point has a resistor divider that leads to the respective pin on
the chip that is the voltage input to the ADC. These inputs are
spade terminals on the bottom of the board.
Caution: High Voltage! Do not touch these pins!
4
J1
5 Volt external
supply
Plug for connecting the external 5 VDC power supply.
10
SW2
RESET
Chip reset switch: When the switch is pressed, the RESETZ
pin is pulled low, which resets the IC into a known state.
11
J12
Test Point for the
Optical Interface
Five-pin header allowing access to the OPT_RX and OPT_TX
signals. Pins 1 and 2 can be used to connect a LED. Pins 3, 4,
and 5 can be used to connect a photo-transistor.
12
D5
WATTS
Red LED. This LED functions as a pulse output for test and
calibration (Wh).
13
JP6
GND, DIO3, V3P3
Three-pin header. This header can be used for general
purpose DIO.
14
TP15, TP16
GND
GND test point
15
TP20
SEG26/DIO06
Two-pin header. This header can be used to pick up the signal
for the VARS LED output.
16
TP21
SEG27/DIO07
Two-pin header. This header can be used to pick up the signal
for the WATTS LED output.
17
D6
VARS
Red LED. This LED functions as a pulse output for test and
calibration (VARh).
18,23
J11,J10
--
Two 2x12 headers for the LCD connection. The LCD daughter
board plugs into the male (J10) and female (J11) headers.
19
JP12
DIO Test Point
9-pin header for monitoring DIO15 to DIO21.
20 JP13,JP14,
JP15
DIO00, DIO01,
DIO02
Three two-pin headers for monitoring the DIO00, DIO01, and
DIO02 signals.
